-To all whom t may concern:

Be it known that l, JOHN Hour, a citizen of the United States, residing in the cit and county of San Francisco andState of C litornia, have invented new and useful Improve-- ments in Extension-Couches, of which the following is, a specification.

My., invention relates to improvements in couches which are capable ot being extended so as to form beds when required.

It consists in a combination of parts and in details of construction, which will be more fully explained byA reference to the accompanying drawings, in Which- Figure l1 isa perspective view oi my improved couch. v Fig. 2 is a view showing latch thrown outo'l the Way when extension is at vertical osition.

lt is t e object of my inventionto provide a structure which normally forms a couch for ordinary use,y said 'structure having one or more hinged sides capable ofy being; dropped into an approximately vertical position when the device `is used for a couch and Which may be extended into a for use as a bed. y

An. elastic metallic mattress, which forms the top of the main structure and extensions, is made in separate sections, and nieans are provided for stretching and extending it, so as to maintain the surface at proper tension Whether folded or extended.

As shown inthe drawingae represents bases which are formed oi angle-iron, the central portion substantially horizontal and having downwardly-bent ends, as shown at a, Whichform feet to rest upon the floor and slightly raise this portion of the structure.' l

` 2 represeents vertical angledron posts having the lower ends bolted -to the transverse portions Aoi the base, and represents the end bars of the main portion oi the couch,

these bars being also made of ang T,le-iron.`

'lhese end 'frames of the couch are `rigidly united together by longitudinal bars, to Which they are bolted, andi the structure is suitably braced for rigidity. The top oi the main portion of the Ycouch is covered `with a mattress, preferably formed oi Woven wire, vas at 4, in'conjunction with the elastic vcables extending beneath the woven wire and upon which the latter rests. This clastic structure is secured at the ends in. the usual manner by' bending' over the frames, and plates or cleats are clamped over these ends to .torni a ii'nish.

horizontal positionl The ends of the extensions 5, of which tWo are here shown, one upon each side of the i 4main body of the couch, are ioriiied of angleiron pivoted to the ends 3 by pins, as shown at o. The outer 'ends oi these angle-iron endpieces are connected by bars 9 riveted thereto, and these bars are curveddownwardly between the ends, so that when the extensions arein a horizontal position the edges of the elastic mattress Will not come in contact with these connectingbars. Each ofv these extension structures is covered with elastic metallic fabric similar to .that I describe for the main structure and independent thereof.

The contiguous edges ofthe main and suplemental fabric are united by clamps 7' at intervals from end to end, so that when the extensions are bothopened into horizontal ositiona continuous elastic surface is formed rom the extreme outer edges of the extensions. y

In order to further increase the transverse tension ol" the mattress structure, 1,' have shown links or hooks 9a, by which the cables 8 may be extended transversely and connected With the bars 9 which form 'thejoiiter edges of' the extensions. The outer cables `oi the extensions being thus connected lwith these exterior bars' and the contiguous edges of the main and supplemental mattress beingr united by clips 7, as previously described, it will be seen that the tension thus produced Will be transmitted across the main and supplemental structures, and thus produce avery even body-surface Without und-ue variation in tension ci the diderent parts;

lt Will be noted that the pivoting of the extension end sections 5 to the central enf"l sections. When the extensions are raised and standing in line with the central section, the` edges o'iithe fabric being,l substantially inline above the pivot-pins will be close together at the ends; but When the extensions are turned `dovvii'viardly to forni a couch these Yedges Where vthey are attached to the end sections Will be separated, as shown in the drawings, and this separation taking piace at the ends and, outside of the end clip 7 Will produce a corresponding tension .of the edges, ivliipi. are united by the clip 7, and this servesto maintain this edge niuchn'iore rigid Whenlhe IOS extensions are folded down to forni a couch rihe edge ol" the couch is thus prevented frein being unduly depressed when it is fused a seat. s Y 'l j IIO in traer-t0 hold 'theextensiops 5 in'their' vhorizontal position when raised ,I have shown.-

braces having the 'outerends n xed to theextensions and slidable through slots 10 in the posts 2. These braces are curved in a sort of cam shape having its greatest curvature at the points nearest to extensions 5, as shown at' 11, the curvature becoming less toward the inner and free ends of the braces, so that when the extepsions are closed down to form the couch the "'nner ends Iof the braces will be thro'wn up inside of and beneath `the angleiron end pieces 3 and entirelyout of the way of4 the bedclothes, this action beingeffected by the sliding of the curved portion 11 through the slots in the posts 2 at the instant when the extensions are closed.v l Y In order to hold the extensions in a h'orizontal'position when raised and to provide an easy means for latching and disengagin the latches, I have shown the inner ends' o the of the'slots l 'of the posts .2.v There bemgi one of these latch-arms-at each end of either "extension, the parts will thus be held firmly f Vin place.` In order to dsengage these latches and allow the extensions to drop into a verti` cal position, I have shown'. the ends of camlevers beyond the notches 12-1nadehigher than the portion anterior Ito the notch, 'asshown at 13.

When it is desired to unlatch and-depress the extensions, the outer ed e ofthe'iextension is first lifted slightly. f .causes the notch12 to disengage from the slots 10 of the posts 2, and the further withdrawal of the "bracefwil'l causes' the elevated portion y13 to ride upon the lower edge of the slot 10.- The outer' end of the brace alsocurv'ed, as shown,"ffand after the edge of the extension has been raised-by suddenly dro it the raised portion 13 of the brace libldit so Ymuch above the bottom of the slot 10 that, the sudden motion of drop ing the extension.

will cause the brace to sli e through the slot 10 and move @so far 'before .it dro s in the slot that it will have passed the late .-slot 1\2,' so that the latter will not engage. `The ex: tension being then dropped into its vertical' position, the sharp curve or cam 11 will -act "as previously described and will serve to throw the inner end of the brace np into` the angle oftheybar 3 and out of the Way. It

will be seen by this ccnstruction'that either one orboth extensions may be em lo ed. If only one be used, a three-quarter `e will .be

formed. If both are used, a double may' be provided. The supplemental mattress which forms the body of the couch normally remains upon the couch for use. Whenthe extensions have been raised to form a. bed, this portion may be slipped over toone side,

and the supfpleinentary mattress is laidbe- As the sum of thewidth' of the two extensions isusually not as great as the width of the main cpuch-surface, this supplementary mattress be somewhat narrower than the mainone, d the joint between the two Will be at one side -ofthe middle, but not coinciding With,the 'oint ofthe'elastic metallic mattress beneat When the couch is in'use, the supplementary mattress is placedbeneath which ifiorms a portion of the couch and falls to the oor.

shown parallel longitudinallydisposed rods 14, extending from end to end between the bases'A, and other rods 15, slightlyV elevated above the rods14, extending between the vertical posts2, which practically form-sides to` prevent the mattress from sli ping out sidewise. These rodsl form smootli surfaces with very little frictional resistance, and the lmattress can Abe pushed in from either end and rest vsecurely upon the rods. Bedcloth- "mg" may be folded and piled upon the mattress andi the wholeof the urnturenecessary for the bedbe conveniently concealed within .the body of the couch.

The longitudinallydisposed cables 8, upon i which the woven-wire portion of the mattress "rests are separatedtransversely and united =mattresses, andfby thus separating the casionl is' provided. 'y l In .my improvements I have provided for the increase and adjustment of'this tension by means of sup lementary slidable clips, as

' shown at 16.- lPhese clips are nearer to the of divergence will be increased and corresponding increase of tension will be effected.

Having thus described my invention, what l' claim, "and desire-to secure by Letters'Patent, is

1. The combinationvwith a'frame bearing a stationary locking-shoulder, and a swinging leaf pivoted thereon, of a bar-form lockprovidedat its lower edge near its inner end with a narrow notch, the' lower edge of the inner end'of said link riding on said lockingshoulderwhen the leaf is raised above the and for the purpose set forth.

'lhe combination with a frame side it, thus orming the full-.Width of the bedl In order to conveniently introduce and rel move this supplementary mattress, I have by vclips. inthe "usual ,v construction of such'.

ICO vbles tpansversely the certain amount of ten l ends of the mattress than the main uniting clips, and as' the cables diverge between these l clips to the ends it will be manifest that 'bymovingthe clips toward the ends the angle.

the couch and is concealed by the drapery ing-link pivoted at one end on said leaf and horizontal, thereby to elevate the notch so v -that the acquired momentum of the parts.v and inertia ofthe link will be sufficient to "cause the notch 'to clear the locking-shoulder whenv the leaf is dropped, substantially'as a stationary ioc'king-sho11lder, and aswinging leaf pivoted thereon, ofa bar-form lockinglink pivoted at one end on said leaf and having a straightlower edge provided with a notch near its inner end, the lower edge of v said inner end riding on the lockin -shoulder when the leaf is raised above the orizontal position, whereby the notch-is elevated .suffe ciently to clear the lookin -shonlder when the leaf is dropped from'an a normallyhigh positiOn, substantially as. and'for the purpose set forth, l
